Extended Outlook

Current radar

Partly cloudy warm and muggy with isolated showers western areas and near the coast.

Expect scattered to numerous showers and t-storms with locally heavy rainfall possible especially over the Brazos Valley and western counties.

Locally heavy rainfall could result in minor flooding. The greatest risk of flooding will remain over the far western counties and Brazos Valley.

High rain chances will continue across SE TX through the weekend as deep moisture remains in place and a slow moving front crosses the region. Slightly cooler and drier weather are expected early to mid next week behind the front.

Expect southeast winds to increase to 20 to 25 knots overnight with seas building to 5 to 7 feet.
